Product Information

Full details

The SOMA Pulsar-23 - Rusty is an organismic drum machine for electronic musicians and sound designers seeking unique, non-acoustic percussive textures and complex rhythmic patterns. Its key benefit lies in its vast creative potential through a semi-modular design with 23 independent modules, allowing for unparalleled sound sculpting. A caveat is its inherent complexity, requiring an investment in learning to fully harness its capabilities.

FAQs

What type of sounds can the Pulsar-23 create?

The Pulsar-23 is designed for unique, non-acoustic synthesis. It can create a wide range of percussive sounds, complex rhythmic patterns, basslines, melodic sequences, evolving soundscapes, and experimental effects.

Is the rust finish durable?

Yes, the rust finish is a stable, intentional aesthetic treatment. It is designed to be durable but should be cleaned gently with a soft cloth to maintain its appearance.

Can I integrate it with my existing modular synth setup?

Absolutely. The Pulsar-23 features extensive CV inputs and outputs, allowing it to seamlessly integrate with Eurorack and other modular systems for control and sound generation.

Does it require a specific power supply?

Yes, the Pulsar-23 requires its dedicated power supply, which should be used for optimal performance and safety. Always use the provided adapter.

Can I trigger sounds externally?

Yes, you can trigger sounds and sequences externally using MIDI Note On/Off messages or Control Voltage signals like Gate and Trigger.

What is the benefit of its semi-modular design?

The semi-modular design offers immense flexibility by allowing you to re-patch signals between its 23 modules. This enables deep sound design and the creation of complex, evolving sonic textures beyond fixed-architecture devices.

Does it produce clean, acoustic drum sounds?

No, the Pulsar-23 is an 'organismic' drum machine and focuses on unique, synthesized, and experimental sounds. It is not designed to emulate acoustic drum kits.

Troubleshooting

No sound output

Ensure the main audio output is correctly connected to your mixer or interface. Check that the volume levels are turned up on the Pulsar-23 and your connected equipment. Verify that the unit is powered on and all necessary modules are active.

MIDI or CV control not working

Double-check all MIDI and CV cable connections to ensure they are plugged into the correct input ports. Verify that the MIDI channel or CV signal is configured correctly on both the Pulsar-23 and the external controller/sequencer.

Unwanted noise or distortion

Reduce gain staging on your mixer or interface. Some modules produce high-gain or intentionally distorted sounds; adjust module levels and routing to achieve desired results. Ensure all audio cables are properly shielded.

Unit does not power on

Confirm that the power adapter is correctly connected to both the unit and a functioning power outlet. Check the power adapter itself for any visible damage.

Pros and Cons

Pros

  • Offers a truly unique and experimental sound palette not found in conventional drum machines.
  • Extensive semi-modular architecture provides deep sound design possibilities.
  • Robust build quality with a distinctive aesthetic.
  • Can function as a versatile sound design tool beyond just percussion.
  • Excellent for creating complex, evolving rhythmic patterns and soundscapes.

Cons

  • Steep learning curve due to its complex and non-traditional interface.
  • Sound output is intentionally abstract and may not suit users seeking realistic drum sounds.
  • Requires external audio interface or mixer for use.
  • The rust finish, while unique, may require specific care to maintain its appearance.

Setup, Compatibility & Care

Setup: Connect the main audio output to your mixer or audio interface. For MIDI or CV control, connect the relevant cables to the designated input jacks. Ensure all connections are secure before powering on.

Compatibility: The Pulsar-23 can be controlled via MIDI (Note On/Off, Clock) and Control Voltage (Pitch, Gate, Trigger, Clock). It is compatible with standard Eurorack modules for CV patching. Audio output is line-level.

Care: The rust finish is intentional and designed to be stable. Avoid abrasive cleaners or polishes, which could damage the finish. Clean the unit with a soft, dry or slightly damp cloth. Protect from extreme temperatures and humidity.
